Alzheimer's disease, Dementia, Essential Oil Therapy

Essential oils in the treatment of Alzheimer’s disease and dementia

4 Comments

Alzheimer’s disease is a progressive, degenerative disease of the brain, which causes thinking and memory to become seriously impaired. It is the most common form of dementia. Dementia is a syndrome consisting of a number of symptoms that include loss of memory, judgment and reasoning, and changes in mood, behaviour and communication abilities.1

There has been research to support the use of essential oils for aiding with cognitive function, agitation, behavioural issues, aggressiveness, memory enhancement and mood. Essential oils such as rosemary (Rosmarinum off. verbenon), peppermint (Mentha piperita) and lemon (Citrus limonum) are known to enhance memory and alertness. Oils such as lavender (Lavandula angustifolia), orange (citrus senensis) and ylang ylang (Cananga odorata) are known for their sedative, calming and antidepressant properties.2 To increase alertness, I recommend oils such as rosemary, basil (Ocimum basilicum), peppermint and lemon. Oils to aid with sleep and restlessness include lavender, Roman chamomile (Anthemis nobilis), neroli (Citrus aurantium amara) and mandarin (Citrus reticulata).

Also, research has shown that although there is an olfactory dysfunction in people with Alzheimer’s disease (AD), the loss of one’s sense of smell does not affect the essential oils effectiveness, as they work at a physiological level. The oils are inhaled through and absorbed by the lungs and through the skin and are effective due to their chemical make up. It is believed that the loss of smell may be an early sign of Alzheimer’s and other neurodegenerative diseases.

One of the most popular essential oils and one shown to be beneficial with Alzheimer’s, is lavender. A hand massage with lavender essential oil has shown to help with emotions and reduce aggressive behaviour in elderly with Alzheimer’s type dementia.3

In another study, lavender and orange were used in the evening, and rosemary and lemon used during the day with 28 patients with dementia, of which 17 had AD. All patients showed significant improvement in orientation related to cognitive function. Laboratory tests after this study showed that there were no side effects with the use of aromatherapy.4

Acetylcholinesterase, aka AChE, is the main target for many drugs to treat AD and dementia. AChE is an enzyme, which degrades the neurotransmitter acetylcholine. Thyme (Thymus vulgaris) essential oil and its compounds, thymol, linalool and carvacrol, were found inhibit AChE.5

In a placebo controlled, double blind study, sage (Salvia officinalis) and Spanish sage (Salvia lavandulaefolia) have shown to increase the speed of memory and enhance mood.6 An earlier study showed that Spanish sage inhibits the enzyme acetylcholinesterase (AChE).7 Black pine (Pinus nigra) has also shown to have AChE and butyrylcholinesterase (BChE) inhibitory activity.8

Another placebo controlled trial with lemon balm (Melissa officinalis) was conducted in a health care facility to assess treatment for agitation in patients with severe dementia. Sixty percent of the active group showed a 30% decrease of their CMAI agitation (Cohen-Mansfield Agitation Inventory) score.9

Some people who suffer from AD and other forms of dementia, experience Sundowner’s Symdrome, named so as these confusion symptoms appear after ‘sundown’. These symptoms can include restlessness, wandering, depression, agitation and hallucinations. Many of the essential oils mentioned can be used to aid with these symptoms.

Applications, which have been used successfully in nursing homes and at home, include inhalation of the essential oil, a room spray made with the appropriate hydrosols, use of the essential oils in a diffuser, adding a few drops to a bath or onto a pillow and a custom made inhaler for personal use. As more research and clinical trials are completed, aromatherapy (essential oil therapy) will become more recognized as an accepted and evidence based alternative to pharmaceutical drugs.

For those of you who have a family member with AD or are caring for one, there is an amount of stress involved in caring for your loved one and a feeling of helplessness. There are a number of essential oils to aid with stress, depression, anxiety and panic attacks.

ADHD, Essential Oil Therapy

Essential Oil Therapy; treating ADHD

4 Comments

Attention Deficit Hyperactivity Disorder (ADHD) is a neurobiological disorder. Note that the term ADD (Attention Deficit Disorder) is no longer used. ADHD is now classified into three categories, one of which is formerly known as ADD, and is based on three core symptoms: inattention, hyperactivity and impulsiveness. There are a number of chemical properties in certain essential oils, which may be effective in treating ADHD. These oils include basil, cedarwood, chamomile, frankincense, lavender, mandarin, melissa, neroli, rosemary, sandalwood, vetiver and ylang ylang. Below are some of the essential oils best suited for treating ADHD:

  • Basil (ocimum basilicum); a cerebral stimulant, enhances concentration and aids with mental fatigue.
  • Cedarwood (cedrus atlantica); a sedative, has a relaxant affect on the parasympathetic and sympathetic nervous systems.
  • Frankincense (boswellia carteri); also contains sedative properties, can be used for nervous tension and anxiety, and is often used during meditation.
  • Lavender (lavandula angustifolia); one of the most popular oils and is known for it’s sedative, calming and soothing properties.
  • Mandarin and Neroli (citrus reticulata/aurantium) essential oils; known for their anxiolytic properties, which relieve stress, anxiety and depression.
  • Vetiver (vetiveria zizanoides); a sedative for the nervous system, is used for stress related ailments and is very relaxing.

A pure essential oil blend, which may be effective in working with ADHD, is our Mental Clarity inhaler. This product contains peppermint, rosemary, lemon and basil essential oils, in an essential oil inhaler, which is a convenient way to use essential oils, especially for children. This particular blend of essential oils are known to aid with concentration, memory and retention, and alertness. There are also a number of applications in which essential oils can be effective. If a pure essential oil blend is being used, a few drops can be added to the bath, to a carrier oil or to a natural, unscented lotion and then massaged onto your back, chest and feet. Essential oils can also be added to a diffuser, or a few drops put on your pillowcase, a cotton ball or tissue.

The same combination of essential oils will not be effective for everyone. Certain oils compliment each other and their synergy enhances the effect of the other oils. Each of us are unique, which is why a custom formula may be right for you. As well, take a close look at your child’s, or your own, diet, environment, stress levels, and happiness, which all have an affect on their/your behaviour. In the end, it may not be ADHD at all. Research related to nutrition shows that a diet high in essential fatty acids and vitamin C improves the symptoms of ADHD. Another study published in The Lancet medical journal, has shown that artificial food colouring and additives have been linked to ADHD like behaviour.

Essential oil therapy can be an effective complementary treatment for ADHD. Along with a proper diet and a healthy lifestyle, the symptoms of ADHD can be greatly reduced, and for some totally eliminated.
